PYROPHOROUS LIGHTER.

Specification of Letters Patent.

Patented Apr. il, t 9113.

Application filed April 16. 1912. Serial No. 691,131.

To all wiz-0m z' may concern Be it known that l, O'r'i'o Statuen, ofBerlin, a subject of the King of Saxony, and whose post-oilice addressis Steinmetzstrasse 31, in the city of Berlin, Kingdom of Prussia,German Empire, have invented a new and useful Pyrophorous Lighter, ofwhich the following is a specification.

This invention relates to pyrolihorous lighters, that is to say, tolighters in which a spark is produced by rubbing a spark producingmaterial, for instance cerium-iron or the like,.the said spark beingadapted to light a wick impregnated with inflammable liquid such asbenzin or the like or a piece f of tindei. In such lighters a milled4wheel is quickly rotated by a spring or the like, whereby a spark isproduced from the spark producing. material, or a rod-like holder, isemployed which as a rule is mounted in the casing containing an'impregnated wick, and is itself provided with such a wick, the holderbeing withdrawn from the casing and rubbed like a match on a rubbingsurface of the cas-ing and is thus ignited.

This invention relates to an improvement i in lighters of the latterkind. In' these lighters, hitherto it has been usual to secure in ametal sleeve a shortJ piece of spark producing material such ascerium-iron or the like, by means of cement. When the said short piecewas worn away by repeated striking, it was necessary to dissolve thecement and to insert a new piece. This manipulation is not onlycomplicated,'but can not be done by the customer himself. The drawbackis obviated according to this invention by employing a rod of sparkproducing material, of practically the same length as the holdingsleeve, inserted in the holder used for striking, in an easilydetachable and adjustable manner through the cap containing the burningwick, in the same way asa lead is introduced into a pencil. Theinvention has therefore the great advantage that in such a lighter thelength of life'of the pyrophorous material without renewal sconsiderably increased, and the adjustmlimt of the lighting rod can beeasily effected at any moment by the user.

A construction according to this invention is illustrated by way ofexample in the accompanying drawing in which- Figure 1 is a longitudinalsection, while Fig. 2 shows the bottom part. of the holder sleeve inelevation, turned at 90o from the position shown in Fig. 1.

In the drawing, the rod a of spark producing material is fittedA looselyinto the central bore of a sleeve made of metal. This sleeve is providedat the bottom with a screwthread c' on which is screwed a screwthreadedcap c. The sleeve is made with a tapering bottom end (l and providedwith slots n, so that the conical end of the sleeve b is slightlyspringy. The cap c is also made of a corresponding conical'shape, asshown in the drawing, so that, when it is screwed on, the conicaltongues (Z of the sleeve I) are firmly pressed against the rod a andhold it fast, while when the cap e is unscrewed, the rod a can be easilyadvanced.

In front of the conical portion, the cap c is provided with tongues 0between which preferably are arranged slots and between which is jammeda wick f of non-combustible material such as asbestos-wool, glasswool orthe like. At the upper end the sleeve b is provided with a button Lforming a handle and with a widened conical part y' fitting exactly intoa conical branch k of the casing z' of the lighter, to one side of whichis secured the rubbing surface Z. The button /L is preferably providedwith a longitudinal perforation g through which a pin or the like can beintroduced in case the rod a should stick fast in the sleeve b. To thebranch c of the casing z' is secured a tubular wick m.

The method of use is as follows After having withdrawn from the casingz' the holder consisting of the sleeve b, the pyrophorous bar a and thewick cap e, a little liquid such as benzin or the like, is introduced,until the wick m. is .impregnated therewith, whereupon the rest of theliquid is poured off. The holder is then introduced into the casing.During withdrawal the ignition wick f becomes sufliciently impregnatedwith benzin, so that on the holder being rubbed with the ignition bar aon the rubbing surface Z the wick f is lighted by the spark. After use,and after extinguishing the flame, the holder is replaced. If after acertain time the ignition bar a has worn down to the edge of the wick f,so that the said wick j andthe spring tongues 0 would be damaged byfurther use, the Wick cap e is somewhat unscrewed, and the ignition bara is advanced to the ,same extent.

The ignition bar a can then be easily adj listed at any moment and useduntil it is all wornout down to a slight length. Obviously it' it weredesired, instead of producing a. flame, to make a piece of tinder glow,the wick f could be replaced by tinder.

lVhat I do claim, and desire to secure by Letters Patent of the UnitedStates, is

An ignition apparatus of the character described, comprising incombination a casing, a tubular holder removably inserted into thecasingr a rod ot' spark producing material loosely inserted into theholder, an annular wick surrounding the lower end of said rod, conicaltongues on the lower end of said tubular holder and a screw threaded capitting with a. conical recess on the conical tongues and provided withtongues for holding in position said annular wick.

ln testimony whereof I have. hereunto set my hand in presence of twosubscribing wit nesses.
